Answer:
The numbers are 16 and 20
Step-by-step explanation:
Let the multiples be: x+4 and x+8
Sum is 36, so we can make an equation:
x+4+x+8=36
2x=36-12
x=12
The numbers are 12+4=16, 12+8=20.

It’s -3 repeating and there is the work your welcome child
They are all different sizes.

=====================================================
Explanation:
By definition, 
Squaring both sides gets us 
Then multiply both sides by i to get 
Repeat the last step and you should get 
---------------
Notice we have this pattern going on:

Once we reach i^4, we start the process over again.
It repeats every 4 terms.
This means we'll divide the exponent over 4 and look at the remainder. We ignore the quotient completely.
157/4 = 39 remainder 1
That remainder 1 is the exponent of the simplified term

---------------
Similarly,
315/4 = 78 remainder 3
So 
---------------
102/4 = 25 remainder 2

----------------
76/4 = 19 remainder 0

16x11 which equals 176 so that’s the area
